Everywhere I've heard it, "P" is for propeller (full forward, in
case of a go-around).  Like "undercarriage", applies mostly to 
complex planes.

People wanting to mention carb heat do C-GUMPS.

I was taught, and do, GUMPS checks on downwind, base, and final
when I'm flying a controllable prop plane with retractable gear.

Otherwise, I don't like it (personally).  Because you are constantly
mentioning two things you have absolutely no control over in a fixed
pitch prop, fixed gear plane, to me it encourages the chanting of
checklists like mantras without meaning or action attached.

On the other hand, that's just my opinion and in any large enough
gathering someone can be counted upon to express the heated opinion
that failing to do GUMPS checks from the start is bad piloting sure
to produce a gear-up landing some day.

Me, I make up my own little chant appropriate to the plane I'm
flying.  Since my current plane does not recommend carb heat in
the pattern, has low wings, and is usually leaned for most flights,
I want to check the fuel pump (on) and the mixture (rich) in the
pattern.  People who fly with me can tell you I actually say aloud
"fuel pump on mixture rich" while making it so just before I reach
the numbers on downwind, and touch these while saying it again
on final.

I've never heard the F before, but I suspect you're correct.

I would suspect "E" for engine (since the point of carb heat is to
keep the engine from stopping).

That's another thing I'm not fond of in these mnemonics--to me,
they aren't mnemonic.  How often do you hear pilots talk about
"fixed undercarriage" or "retractable undercarriage" planes outside
of these lists?  Isn't it usually "gear"?  How often do you hear
American pilots talk about "gas" outside of these lists?  Isn't it
usually "fuel"?  Fuel flow, fuel capacity, fuel reserve, fuel tester....

Ah well.
